FIELD: mining.
SUBSTANCE: method includes drilling out the field by the dispersed pattern using multibranch wells. Water and/or gas are used as working agents for maintaining strata pressure. According to the invention the size of an element of the dispersed pattern of dislocation of wells is increased multiply and is accepted so as to keep the actual flow rate with this number of wells not in excess of the capacity of tubing and/or capacity of the equipment used for mechanised oil production. The boreholes of the multibranch well are dislocated on lateral edges of the dispersed pattern element. The injection well is also drilled in the variant of the multibranch. This well is located in the centre of the dispersed pattern element and the boreholes are dislocated at the angles of the dispersed pattern element of development of the field.
EFFECT: increased efficiency of development of the field is provided.
